If I purchase say a new coffee pot should I be able to sell coffee on the street corner for the same price as Stabuck's and call it just as good?

If I were to purchase a new fancy sewing machine would you hire me to make your wedding dress?

 Just because I purchase a race car does it mean I belong side Earnhardt at the Daytona 500

 If I were to purchase a high speed buffer would you let me buff your brand new expensive car you worked hard to save for?

My reasoning being, just because entry level DSLR camera are so reasonably priced it wont make the person buying one a Professional Photographer.

You'll hire a professional to cook your meal. You'll hire a professional to make your dress.

You'll hire a professional Limo service to get you to your wedding.

But yet a guy with an entry level camera he purchased will wreck your expensive day and he will charge you professional rates because he has the gear.
